Specication of Letters Patent.

Application led September 10, 1915. Serial No. 50,010.

To all 'whom t may concern:

Be it known that we, MARLEY FOTHERING- HAM HAY, a subject of the King of England, residing at Carel van Bylandtlaan 4, The Hague, Netherlands, and CORNELIUS EKAMA, a subject of the Queen of the Netherlands, residing at Willemstraat 71, The Hague, Netherlands, have invented certain new and useful Improvements in Apparatus for Moving Diving- Rudders of Submarines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an apparatus for operating the diving rudders or hydroplanes of submarines by means of which it is possible to set such rudders in any suitable position when the boat is submerged and which allows the rudders to be stored in the superstructure of the boat when the said boatis running on the surface of the water.

For enabling the rudders to be set into di'erent positions for diving purposes,V they are connected to the ends of a shaft, which shaft is mounted transversely across the hull of the boat, so that by turning the shaft the'irudders can be brought into any required position. '.lo enable the rudders to be stored in the superstructure of the boat, they are pivotally mounted upon studs 'xed to the end of the said shaft, the axis of these studs being perpendicular to the axis of the shaft, so that when the said shaft is turned Vto bring the rudders into a horizontal position, such rudders can be moved in their own plane so that they pass through a slotted opening in the side wall of the superstructure and are brought into a Vspace formed for their reception above the hull of the boat. Y Y

The accompanying drawing shows one method of carrying out the invention.

Figure 1 is a vertical cross section through the axis of the shaft ofthe apparatus forming the subject of the invention.

Fig. 2 is a topplan of the apparatus.

1 are the rudders which in the drawing are shown in full lines in the stored position, and in dotted lines in the working position. 2 is the hull of the boat, provided with a superstructure the side walls of which are indicated by 3. A shaft formed 1n two pieces 4 and 5, is provided extending transversely across the boat. The pieces 4 and 5 are connected together by a flanged coupling 6 and supported by the bearings 7, 8, 9 and 1() fixed to the hull 2. Y

At the outer ends of the shaft 4, 5 are provided eyes 11, over which fork-shaped portions of the rudders 1 engage. Through the eyes 11 and the fork-shaped portions are passed studs 12 so that the rudders 1 can be moved relatively to the shaft 4, 5.

When the rudders l are set in the working position, that is to say in the positionrindicated by dotted lines in both the figures, they may be turned into different directions for diving purposes by rotating the shaft 4, V5 by means of'a lever 13, connected to links 14 (Fig. 2) which can be operated from the control'station inside the boat.

The mechanism for turning the rudders upon the'studs 12 is so constructed that it does not interfere with the rotation of the shaft 4, 5. l'

The mechanism comprises a sliding sleeve 15 which can move along a key 16 on the part 5 of the shaft. This movement is effected by means of a threaded spindle 17 upon which works a traveling nut 18. The traveling nut 18 is connected to a slip ring 19 which lies within a groove in the sliding sleeve 15. The spindle 17 is rotated by means of bevel gearing 20, 21 from a shaft 22, operated from the control station, so that the sliding sleeve 15 can be moved along the portion 5 of the shaft.

At each side of the sliding piece 15 are provided projecting armsl 23 and 24, having pivoted to their ends links 25 and 26. The link 25 is connected by means of an arm 27 to the larboard rudder while the link 26 is directly connected to the starboard rudder by means of an eye 28.

The mechanism for moving the sliding sleeve 15 also could be obtained by using a lever, on a vertical shaft, and connected by two links to two pivots on the top and under side of the slip ring 19, the operating of the lever from the inside of the boat giving "the stroke necessary for moving the rudders in or out, the mechanism being so arranged that in the working position of the rudders the operating lever and the l Vso I pulled; outivard and; the;Y starboard Y rudder to'bepushed outward, the horizontall movement. of Vsuchzrudders being limited by the sliding sleeve Y 15 coming Vinto Contact Y .iththe surface of thefsupport as shown Y Y VVindott'ed lines-at p In the VWorking positionV of the diving rudders, the diving movement as previously stated'is obtained by .operating the lever 13,

thersliding sleeve turning at the same time freely in the'slipring 19. `In the stored Y' position! of the diving rudders the sliding Sleeve lwcomes against the surface of the *Y Y bearing Owing =to the friction between Y"vil' i i.

i v Y Whatever .position the mechanism is set, se

the screw and nut connection v17, 18, Vin

A' icurityv isi-automatically obtained.
